UPDATE
Right team, so far so good. My JetBox is in the air again after having it's starter generator replaced. Once it was done and I pressed the starter it motored through 12% (a previous sticking point) up to 14%/15%.
A subsequent start on my APU was just as good and it seems a happy bunny now. We'll have to see how the next few starts are, particularly, the first one's of the day.
Thanks very much for all your help.
